pull a gremlin

To get mean and ugly when drinking. Just as the Gremlin of 80s mythology multiplied when wet, so can the ugliness of some people grow when drinking malt liquor or other nasty alcohol.

Sorry I pulled a gremlin last night...I guess I've been kinda stressed lately and 120oz of King Cobra didn't help.

Don't pull a gremlin again or you're cut off the Colt 45, dude.
